The alpha motor clearly dissociates the hot source from the cold source. In fact, one cylinder heats gas, another cools it. The kinematics is such that one passes the gas from one cylinder to the other. See below a brief study of this type of motor.
Mechanical configurations of Stirling engines are generally divided into three groups known as Alpha, Beta and Gamma arrangements. Alpha engines have two pistons in separate cylinders that are connected in series by a heater, regenerator and cooler. Both Beta Gamma engines as used mechanisms displacer-piston engine has the Beta both the displacer and piston in cylinder system online, while the Gamma engine uses separate cylinders.
Alpha engine is conceptually the simplest configuration of the Stirling engine, however suffers from the disadvantage that both hot and cold pistons have seals need to contain the operating gas. There are a number of mechanical mechanisms that allow this engine to function properly with the correct phasing of the two pistons. An excellent animation of the Alpha type V engine developed by Richard Wheeler (Zephyris) from Wikipedia is shown below:
Andy Ross of Columbus, Ohio, has been designing and building small engines air from the 70s, including Alpha extremely innovative designs. He is the inventor of the classic Ross Yoke engine and a balanced "Rocker-V" mechanism, both shown below.
